HAIB-TBIMMER.

Specification of Letters Patent.

Patented Aug-14, 1917.

Application filed January 8, 1917. Serial No. 141,284.

Be it known that I, NORMAL G. Gone, a

citizen of the United States, residing at Plainfield, in the county of Union, State of New Jersey, have invented a new and useful Hair-Trimmer; and I do hereby declare the following to be a full, clear, and exact description of the invention, such vas will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a safety hair trimming ,device, and has forits object to provide a device of this character which embodies novel features of construction whereby a person can easily trim his own hair in a very satisfactory manner.

Further objects of the invention are to provide a device of this character which is comparatively simple and inexpensive in its construction, which can be manipulated with perfect safety, which can be adjusted to trim the hair either short or long, and which will enable the most satisfactory results to be obtained without the assistance of a professional barber.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of a hair trimmer constructed in accordance with the invention.

Fig. 2 is a horizontal sectional view 0 the line 22 of Fig. 1.

Fig. 3 is a transverse sectional view on the line 33 of Fig. l.

Fig. 4 is a detail perspective view of one end of the blade.

Fig. 5 is a similar view of the clamping bar.

Fig. 6 is a detail perspective view of the adjusting yoke and screw.

Fig. 7 is a transverse sectional view on the line 7-7 of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describing the present embodiment of the invention, the numeral 1 designates the back ofthe main frame, said back preferably having a tapered format1on, and being'provided at one end with a handle 2. A series of resilient guard fingers 3 projectfrom the back 1, said guard fingers having a spaced and parallel relatron to each other and having the extremis t1es thereof returned upon one side of the device, as indicated at 3*. A guide arm at projects from the back 1 at each end of the series of guard fingers, and these guide arms are shown as provided upon the inner sides thereof with L-shaped .slots 5 which open through their outer extremities. The cut ting blade 6 extends transversely across the series of guard fingers 3 and is reversible, being provided at opposite sides thereof with cutting edges o The extremities of the blade 6 are received within the guide grooves 5 of the arms 4 and terminate in lateral flanges 7 which interlock with the said grooves 5. The guard fingers 3 may be sprung to one side when inserting a blade 6 in position or removing it therefrom, although after the blade is properly positioned, the guard fingers are, released, the returned ends 3 thereof then extending around the outer' cutting edge 6 of the blade so as to prevent any object other than a fine member such as a hair from coming into engagement with the cutting edge.

The blade 6 is provided at points toward opposite ends thereof with openings 8 which serve to detachably engage the hooked ends 9 of an adjusting yoke 9. The middle of this yoke 9 has a swivel connection 10 with an adjusting screw 11 which is threaded in the back 1 and terminates in a finger piece 12. With this construction it will be obvious that by manipulating the finger piece the blade 6 can be moved toward and away guard fingers against the blade so as to. hold them securely 1n proper position. x This clamping bar 15 is shown as-provided with key-hole slots 16 which are adapted to interlock with the headed ends of the locking pins 14. W hen the bar 15 is moved l0ng1 tudinally to bring the reduced ends of the .disengage the keyhole-slots 16 from the double headed locking pins 14.

In using the device it is drawn through the hair in much the same manner as a comb, being held at an inclination so that the outer cutting edge 6 of the blade w1ll engage the ends of the hair. The guard fingers 3 prevent the cuttin edge from engaglng and injuring the sea p, and also operating 1n the same manner as the teeth of a comb to straighten the hair so that an even trimming thereof is possible. If it is desired to turn the hair closely, the blade 6 is adjusted to bring the outer cutting edge 6 thereof close to the outer ends of the guard fingers 3,

while ifit is merely desired to lightly trim Y the hair, the cutting blade 6 is moved toward the back 1. It will be understood that the cutting blade is reversible so that both edges thereof can be used, and that when both edges have been dulled it can be readily replaced by a new cutting blade. When the device is in use the guardfingers 3 are securely clamped between the bar 15 and the blade 6, and the bar 15 then engages the hooked ends 9 of the adjusting yoke 9 in such a manner as to prevent them from be coming disengaged from the openings 8 of the blade.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

- 1. A safety hair trimmer including a back, a series of guard fingers projecting from the back and terminating in returned ends, a.

uide arm at each end of the series of guard 'ngers, a reversible cutting blade extending transversely across the guard fingers so as to be shielded by the returned ends thereof, the ends of the cutting blade having a slidable and interlocking connection with the guide arms, and means for adjusting the cutting blade.
